Key legal question
Whether the appeal had to be entered into despite non-payment of the advance on costs.
Extracted holding
No. Because the required advance on costs was not paid within the time limits, the appeal was inadmissible.
Extracted reasoning
The court noted that the advance of CHF 4,000 was ordered and a further deadline granted under Art. 62(3) LTF; the amount still was not paid, so inadmissibility followed under Art. 108(1)(a) LTF.
